It is particularly suitable for large conference rooms, lecture halls, multi-functional halls and other scenes that require high-quality audio and video transmission. It can greatly improve the transmission efficiency and quality of audio and video signals, reduce wiring costs, and meet the needs of various complex scenes.

[0003] In order to ensure the signal transmission quality every time the audio and video distributed terminal box is used, and to prevent equipment failures and extend the service life of the equipment, the audio and video distributed terminal box is usually inspected regularly to discover potential faults and hidden dangers, and to deal with them in time to ensure the normal use of the audio and video distributed terminal box. At present, when inspecting the audio and video distributed terminal box, it is necessary to remove the protective plate installed on the side before inspecting the inside. However, the protective plate is generally installed and fixed with multiple screws. When disassembling, it is necessary to remove multiple screws in turn before removing the protective plate. Such operation is time-consuming and affects the work efficiency of the staff.

[0004] Therefore, it is necessary to provide a new audio and video distributed terminal box to solve the above technical problems. Utility Model Content

[0026] In the specific implementation process, Figure 1-Figure 6 As shown, an audio and video distributed terminal box includes a terminal device 1, a dustproof component for protecting the interior is provided on one side of the terminal device 1, the dustproof component includes a protective plate 2, two clamping plates 3, two pull rods 4 and a plurality of elastic members, a through slot 5 matching the protective plate 2 is provided on one side of the terminal device 1, the protective plate 2 is located inside the through slot 5, and storage slots 6 matching the clamping plates 3 are provided at both ends of the protective plate 2, one end of a plurality of elastic members is respectively fixedly connected to one side of the inner wall of the two storage slots 6, and the other end of a plurality of elastic members is respectively fixedly connected to one side of the two clamping plates 3, and both sides of the inner wall of the through slot 5 opened in the terminal device 1 are provided with clamping slots 7 matching the clamping plates 3, and the side of the clamping plate 3 away from the elastic member is located at the clamping plate 3. Inside the slot 7, one side of the protective plate 2 and one side of the terminal device 1 are both provided with a slide groove 8 for the two pull rods 4 to slide, and the slide groove 8 is respectively communicated with the card slot 7 and the storage slot 6, one end of the two pull rods 4 is respectively fixedly connected with one end of the two engaging plates 3, and the end of the pull rod 4 away from the engaging plate 3 passes through the slide groove 8 and extends to the outside of the terminal device 1, and the end of the pull rod 4 away from the engaging plate 3 is concavely set. Because one end of the pull rod 4 is concavely set, when holding, it can fit the contour of the palm more naturally, reduce the gap between the palm and the pull rod 4, and make the grip more fitting and comfortable. At the same time, the concave setting can form a natural gripping space, which can make it easier and more stable to place the palm on the pull rod 4, and can provide better control;

[0027] The clamping plate 3 is arranged at an inclined position on one side of the clamping slot 7, the elastic member is a spring 9, one end of the spring 9 is fixedly connected to the side of the clamping plate 3 away from the clamping slot 7, and the end of the spring 9 away from the clamping plate 3 is fixedly connected to the inner wall of the receiving slot 6. Both sides of the terminal device 1 are provided with mounting plates 10 for fixing, and the surface of the mounting plate 10 is provided with a plurality of mounting holes 11 for bolts to pass through, a side of the terminal device 1 away from the protective plate 2 is provided with a plurality of heat dissipation holes 12, and a plurality of heat dissipation holes 12 are provided with dustproof nets 13 inside, and a plurality of wiring ports 14 are provided on the surface of the terminal device 1. During installation, bolts are passed through the mounting holes 11 provided on the surface of the mounting plate 10, and the mounting plate 10 is fixed by the bolts, thereby stabilizing the terminal device 1. The air flow inside the terminal device 1 is enhanced through the multiple heat dissipation holes 12 provided on one side of the terminal device 1. At the same time, because a dustproof net 13 is provided inside the heat dissipation hole 12, it can prevent external dust or fine particles from entering the terminal device 1 while dissipating heat, thereby ensuring the normal use of the terminal device 1. The multiple wiring ports 14 provided on the surface of the terminal device 1 facilitate the direct connection of the data cable to the terminal device 1.

[0028] The working principle of the utility model is as follows: when it is necessary to inspect the inside of the terminal device 1, the two pull rods 4 are pulled to make the two pull rods 4 move along the two slide grooves 8 toward the storage groove 6 respectively. Because one end of the pull rod 4 is fixedly connected to the clamping plate 3, when the pull rod 4 moves, it will drive the clamping plate 3 to move into the storage groove 6 and squeeze the spring 9. When one side of the clamping plate 3 is no longer in contact with the clamping groove 7, the protective plate 2 loses its limit and is taken out from the through groove 5, so that it is convenient for the staff to inspect the inside of the terminal device 1. Because one end of the pull rod 4 is concave, it can fit the contour of the palm more naturally when holding it, reducing the gap between the palm and the pull rod 4, making the grip more fitting and comfortable. At the same time, the concave setting can form a natural gripping space, which can make it easier and more stable for the palm to be placed on the pull rod 4, and can provide better control.

[0029] When the protective plate 2 needs to be installed, the protective plate 2 is inserted into the through slot 5, and the two sides of the inner wall of the through slot 5 press the snap plates 3 at both ends of the protective plate 2. Because the side of the snap plates 3 away from the spring 9 is inclined, when the snap plates 3 are pressed on the two sides of the inner wall of the through slot 5, the snap plates 3 are pushed to move into the receiving slot 6, so that the end of the snap plates 3 away from the spring 9 slides along one side of the inner wall of the through slot 5. When the snap plates 3 slide to the position of the snap slot 7 opened on the inner wall of the through slot 5, the snap plates 3 are driven by the rebound force of the spring 9 to move into the snap slot 7, thereby limiting the protective plate 2.

[0030] When installing the terminal device 1, bolts are passed through the mounting holes 11 opened on the surface of the mounting plate 10, and the mounting plate 10 is fixed by the bolts, so as to stabilize the terminal device 1. The air flow inside the terminal device 1 is enhanced through the multiple heat dissipation holes 12 set on one side of the terminal device 1. At the same time, because a dustproof net 13 is provided inside the heat dissipation hole 12, it can prevent external dust or fine particles from entering the terminal device 1 while dissipating heat, thereby ensuring the normal use of the terminal device 1. The multiple wiring ports 14 set on the surface of the terminal device 1 facilitate the direct connection of the data cable to the terminal device 1.

[0031] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0032] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention.
